|Expertise & Infrastructure|
The IT'IS Foundation has dedicated an interdisciplinary team of software engineers, biologists, and radiologists to refining and expanding its database of anatomical models, developing solvers to deal specifically with complex, heterogeneous living tissue, and to develop tools to transform patient medical image data (MRI, CT, etc.) into detailed 3D models through image segmentation, accelerated by image registration of previously segmented models (e.g., the Virtual Population). Modeling is then supported by automatic assignment of tissue properties from the IT'IS database.
With more than 100 Sim4Life licenses, including the Virtual Population 3.x and multiple animal models, and several High Performance Computers (HPC) ranging from Graphics Processing Unit (GPU) clusters to supercomputers, our interdisciplinary research team can tackle highly specific and complex research tasks with superior innovation and efficiency – while ensuring compliance to national and international standards.
